It would be (2,2), because of the opposite reciprocal slope of a perpendicular line.

Answer:

(2, 2)

Step-by-step explanation:

First we find the slope of the line through M and N.  The coordinates of M are (2, 3) and the coordinates of N are (-3, 2).  Using the formula for slope,

m=\frac{y_2-y_1}{x_2-x_1}=\frac{3-2}{2--3}=\frac{1}{5}

For a line to be perpendicular to a given line, the slopes would be negative reciprocals (opposite signs and the fraction is flipped).  This makes the slope of the perpendicular line -5/1.

The coordinates of point K are (3, -3).  Going down 5 units and right 1 unit would put it at (4, -8).  Going backwards, up 5 units and left 1 unit would be (2, 2).  Thus (2, 2) is the point we are looking for.

Find the missing dimension of each triangle described height 14 inches area 245 inches Square
Amiraneli [1.4K]
Given:
Triangle 
height 14 inches
area 245 inches square

Formula in finding the area of a triangle is:

Area = (height * base) / 2

The base is missing, so we need to compute its value using the given figures.

245 = (14 * b) / 2
245 * 2 = 14b
490 = 14b
490/14 = b
35 = b

The base is 35 inches.

A 165 inch pipe is cut into two pieces. One piece is four times the length of the other.Find the length of the shorter piece. Ho
coldgirl [10]

Answer:

Length of longer length=132 inches

Length of shorter length=33 inches

Step-by-step explanation:

Step 1: Determine total length of pipe

Total length of pipe=165 inches

Step 2: Derive expression for all the lengths

We can express all these lengths as follows;

L=l1+l2

where;

L=total length

l1=length of longer piece

l2=length of shorter piece

but;

length of longer piece=4×length of shorter piece

replacing;

l1=4l2

replacing;

L=165

l1=4×l2

165=l 2+4 l2

5 l2=165

l2=165/5

l2=33 inches

l1=length of longer length=33×4=132 inches

l2=length of shorter length=33 inches
